Emaar Properties on Monday announced the roll out of the Dubai Trolley, the world's first hydrogen-powered, zero-emission street tram system.

Moving along Mohammed bin Rashid Boulevard, Dubai Trolley is the region's first-of-its-kind hop-on hop-off transit system that will offer free access for visitors and residents to several iconic attractions in Downtown Dubai.

As part of the initial phase, the driver-operated Dubai Trolley will traverse a distance of 1km, offering hop-on hop-offs at three hotels - The Address Downtown Dubai, Vida Downtown Dubai and Manzil Downtown Dubai.

Operational from 4pm to midnight on weekdays and from 3pm to 11pm on weekends, the double-decker trolley tram can carry 50 passengers.

Three Dubai Trolley stations have also opened and are located near The Address Downtown Dubai, Vida Downtown Dubai and Manzil Downtown Dubai. The Trolley Terminus near Old Town Island will feature F&B offerings.

When fully operational, Dubai Trolley will eventually span 7km across the entire breadth of Downtown Dubai. Several crossings have been provided along the tramway to safe pedestrian traffic.

Ahmad Al Matrooshi, managing director of Emaar Properties, said: "Dubai Trolley is another innovative addition to Downtown Dubai that also redefines the concept of urban mobility. By integrating the unmatched aesthetics of a trolley tram with a state-of-the-art locomotive system, Emaar is presenting a sustainable transport mode for visitors and residents in Downtown Dubai.

"Apart from being environmentally sustainable and enhancing the convenience of the public, it is designed to be another compelling tourist attraction in Dubai. Just as a visit to the city is not complete without a tour of Downtown Dubai, a trip on Dubai Trolley will become a must-do in the tourist itinerary."
